The combination of a carbide stem and ruby ball minimizes deflection and wear, helping you achieve repeatable, trustworthy measurements even during long inspection sessions. The generous 153.5 mm reach enables probing into deeper features or tighter cavities without sacrificing control, while the M4 thread ensures straightforward compatibility with a wide range of fixtures. If your measurement needs require a different ruby ball diameter, additional sizes are readily available on request to tailor the stylus geometry to your app—from delicate contact on small features to robust engagement on larger surfaces. The result is a reliable, easy-to-maintain stylus that supports consistent quality in your metrology workflow.
